> In the latest priority scheduling design, we need to dynamically determine the priority of a queue.
> There are several possible modes:
>  
>  * Leaf queues
>  ** priority.policy = default
>  *** Priority is defined as the maximum priority of any applications with pending tasks + priority.offset, or MIN_INT32 (-2^32) if no applications have pending tasks
>  ** priority.policy = fence
>  *** Priority is always equal to priority.offset, or MIN_INT32 if no applications have pending tasks
>  * Parent queues
>  ** priority.policy = default
>  *** Priority is defined as the maximum priority of any child queues + priority.offset
>  ** priority.policy = fence
>  *** Priority is always equal to priority.offset or MIN_INT32 if no pending tasks exist
> We should expose this as a property of a queue in REST API calls as well.
